This invention relates to certain improvements in web feeding and weboining or pasting mechanisms and is particularly adaptable for use inrelation with a printing machine, and this application is'a dlvlslon ofmy co-pending application Serial No.

687,757, filed January 22, 1924, now Patent No. 1,669,837, dated May15,1928.

According to the present invention, there is provided a support forsupporting a running web roll and a spare web roll with which isassociated a web joining or pasting mechanism including a pair of rolls,one of which is movable toward and from the other,

15 the parts being so positioned and arranged that a spare web may beled from a web roll in either the spare or running position and unitedwith a web running from a roll in the other position to the press.

The invention has for its especial object an improved arrangement of theweb rolls and the pasting rolls, so that a spare web having pasteapplied to its loose end may be simply dropped in either positionbetween the pasting rolls and there be united w1th the running web. 7

A further object of the invention is to provide roll driving devices bywhich the unwinding of the running roll maybe con trolled while the webtherefrom is running to the press.

With these and other objects not specifically referred to in view, theinvention consists in certain novel parts, arrangements and combinationswhich will be described in connection with the accompanying drawings andthe novel features pointed out in the claims hereunto annexed.

In these drawings,

Figure 1 is a diagrammatic side view of the improved web pasting orjoining mechanism and enough associated parts for an understanding ofthe advantages of'the invention, and

Figure 2 is a side view on an enlarged scale of the pasting mechanismshown in Figure 1.

Referring now to these drawings, the invention has been illustrated asused with a multi-couple printing machine employing carrier may beconveniently moved along. the

three active or running webs, in which machine the web pasting orjoining mechanism and the roll supports a'reshown as located abovetheiprintingmechanisms, but it will 1 be understood that the inventionis intended for use and maybe used with other'press arrangements. Asshown, there is employed a three roll machine, the webs of which areindicated by the numerals1, 2 and 3, these webs supplying printingcouples which may be arranged superposed in three decks, the

upper deck only of which is illustrated. Each of these 'decksmay includea pair of er- -fecting couples, each including'form cy inders 4;, 5,impression cylinders 6, 7 and inking mechanism, indicated generally bythe numeral 8, for each-form cylinder, these parts being supported insuitableframing 9. The

'webs from'these couples are or may be slit I and assembled oversuitable guides 10 at a '70 longitudinal former 11.

' In the construction illustrated there is provided for each printingand perfecting cou- "ple a running web roll and a spare web roll,

the running rolls being indicated by the letter R and the sparerolls'fbythe letter S. These rolls are supported in suitable supports 'whichmayvary widely as to character, but in the particular construction. shownthe supports are so arranged that the web rolls are, 'loaded'ther'eintofrom above, As illustrated,

these supports include frames 18 which are formed with bearing portions16 for the roll.

spindles 17 these frames being supported in any suitable manner, notillustrated The rollsma ybe loaded into these supporting frames from atravelling carrier 25 provided with means for lowering a roll, such as apulley 27, cable 28 and hooks 29, and this o.

prising a running web roll and a spare Web roll, a pair of guide rolls94, 95, and located below these guide rolls a pair of pasting or joiningrolls. Each pair of these latter rolls .It will be observed that inthebest constructions and as shown, the web rolls are arranged inhorizontal allgnment with the guide rolls above the pasting rolls. Theend i of a fresh web may have paste applied thereto and be hung over oneof the guide rolls, as indicated at 107 atthe two end positionsin Figurel and the right end of Figure 2, or

the web roll, as indicated in the center position in Figure 1 and at theleft in Figure 2.

if desired the guiderolls 94, 95 need not be used, and the web simplydropped down from When it is desired to effect a paste, the pasted endof the rollis dropped down between the abutment roll 96 and the roll 97and the roll 7 97 is brought into contact with the abutment roll, thussqueezing the pasted new -web against the expiring roll after the pastehas been made. The expiring web may be separated or severed in any usualmanner, as by breaking it with a stick.

-In accordance withthe invention, certain web controlling devices areused for driving the spare roll and for bringing the spare roll up tospeed, and these devices will be such that they will be operated so asto operate on the spare roll at the time the paste is made, so that thepaste may be made withp out stopping the press. -Whi1e the constructionof these driving. and controlling devices may be somewhat varied, asillustrated, 9

they include frictional jfeeding devices which [are driven so as toeffect'the unwinding of the roll with the required nicety of tension. 7

In the particular construction illustrated, these feeding devicescomprise a pair of'belts 34, 35 arranged preferably, as shown, below therolls, one set of these belts being used for each web roll. These beltsaredriven belts,

- being driven from gearing indicated at 76 from any suitable part ofthe press.

With the construction described it will be seen that a 'very simplearrangement has been provided for joining or pasting the end .of anewweb rollto an expiring web, and

that this can be effected whether the web {lead is from under or overthe web roll. While the invention" has been described in its preferred,form, it will be understood that vari- -ous changes may be made in thespecific structure and arrangement shown and described without departingfrom the invention as de fined in the appended claims.

What I claim is:

1. In a web feeding and pasting mechanism, the combination of a supportfor a running web rolland a spare web roll, a pair of pasting rollsbelow the web rolls arranged horizontally, between which a spare web maybe led directly either over or under from a web roll in either position,guides over which the end of a spare web may be suspended and locatedabovethe pasting rolls,vand means for moving one only of the pastingrolls toward theother to join the new web to a web running to the press.

2. In a web feeding and pasting mecha nism, the combination of means forsupporting a running Web roll and a spare Web roll in side by siderelation,,a pair of pasting rolls located below the web rolls andarranged so that spare web may be led from a web rollin either position,guide rolls located above the pasting rolls and over which the end ofthespare web maybe suspended in pasting position, and a single means forbringing the pasting rolls into pasting relation to join the new Webrunning from either position to a web running to the press.

In testimony whereof, I have hereunto set my hand.
